Honda HR195 Owner's Manual page 35

If the grass is not very thick or tall, you can mow a wide swath, and/or you
can move the shift lever to select a fast drive speed. Keep the wheels close
to the swath line for maximum cutting width.
If the grass is very thick or tall, cutting a wide swath may slow or stall the
engine, clog the cutter deck, and cause poor bagging performance. For thick
or tall grass, cut a narrower swath, and/or push the mower more slowly or
move the shift lever to select a slower drive speed. If necessary, mow twice;
first with a high cut, then at final cutting height
For best grass cutting and bagging
performance, the blade must spin very
fast. Always use the FAST ( * )
throttle setting when mowing, and
keep the engine running at or near
maximum rpm. If you hear engine
speed decrease, that means you
should mow a narrower swath, and/or
use a slower forward speed. You may
also need to raise the mower's cutting
height.
Always empty the grass bag before it
becomes filled to the limit of its
capacity. Bagging performance will
diminish after the bag becomes about
90% filled. Also, the bag is easier to
empty when it is not packed full.
Always empty the grass bag when
you have finished mowing, even if it
is not full. Stored lawn clippings are
a fire hazard.
A clogged grass bag will not collect
grass efficiently. If the bag becomes
clogged with dirt, wash it with a
garden hose, and allow it to dry
completely before use; a wet bag will
clog quickly.
